br_sjrpreto_sp writes to clue us to an article on Foodnavigator. Agro giant Bayer Crop Sciences has petitioned the US Department of Agriculture to approve a genetically modified rice variety that has been at the heart of a recent contamination scandal. From the article: "Marketed under the brand name LibertyLink, these [varieties] were engineered to tolerate the toxic herbicide glufosinate ammonium. The company in July notified the US regulatory body that it had discovered trace amounts of an unapproved GM rice in samples of commercial rice seed." After the contamination scare, the market for US rice tanked as European countries imposed import limitations. When rice producers sued Bayer, the company responded with this request to the USDA. The petition is open to public comment until October 10. Comments may be submitted via the Internet at www.regulations.gov — search keyword APHIS-2006-0140."
